CHAPTER 6: ACTUAL VALUES STATUSB30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 6-76stNum — State number. The most recently received value in GOOSE message field stNum. The publisher increments stNumeach time that the state of one or more of the GOOSE message members is sent with a revised value.sqNum — Sequence number. The most recently received value in GOOSE message field sqNum. The publisher sets sqNumto zero each time the state of one or more of the GOOSE message members is sent with a new value, and it increments itwhenever a GOOSE message is resent without any member value change.IGMP — Multicast (SSM and ASM) modes of R-GOOSE reception require that the B30 device subscribe to a multicast groupover the Internet Group Management Protocol (IGMP) enabled network. R-RxGOOSE## IGMP status On indicates that IGMPnegotiation with a network device (for example a router) was successful. In the case where setting R-RxGOOSE1 DST IP isconfigured to a multicast address and this status indicates Off, R-GOOSE reception cannot be successful, and thereforecommunication network diagnosis needs to be carried out. This status is relevant to R-GOOSE reception when configuredfor SSM or ASM reception modes. It is not relevant for GOOSE or for R-GOOSE in unicast reception mode.6.3.10 Digital countersACTUAL VALUES STATUS DIGITAL COUNTERS DIGITAL COUNTERS Counter 1(8)The present status of the eight digital counters displays here. The status of each counter, with the user-defined countername, includes the accumulated and frozen counts (the count units label also appears). Also included, is the date and timestamp for the frozen count. The COUNTER 1 MICROS value refers to the microsecond portion of the time stamp.6.3.11 Selector switchesACTUAL VALUES STATUS SELECTOR SWITCHESThe display shows both the current position and the full range. The current position only (an integer from 0 through 7) is theactual value.6.3.12 Flex StatesACTUAL VALUES STATUS FLEX STATESThe B30 is provided with optional IEC 61850 capability. This feature is specified as a software option at the timeof ordering. See the Order Codes section of chapter 2 for details.
